Community-based climate change adaptation programmes (CCAPs) are designed to enhance resilience among vulnerable populations such as maize farmers in Zimbabwe. A mixed-method approach, including surveys and focus group discussions, was employed to gather data from 150 randomly selected farmers across three regions in Zimbabwe. CCAPs significantly improved maize yields by an average of 25% compared to non-participating areas (p < 0.05), with a notable increase in farmer knowledge about climate change impacts and adaptation strategies. The programmes have proven effective in bolstering the adaptive capacity of maize farmers against climatic variability, warranting their continued support and expansion. Local governments should prioritise funding for CCAPs and integrate them into existing agricultural development plans to maximise benefits for vulnerable communities.
